How many legitimate users will use pluses or dots which you forgot to allow in your email validator?
How many legitimate users will use capital letters, which I had to add to an in-production email validator on an app with millions of MAUs?

You might want to first check that it is not a local address, and to reject it if it is (unless it is being used for an internal registration service). You should also reject it if the destination is unreachable (in which case it is not possible to send a confirmation email, anyways).
